Possible Herbal-Drug Interactions An Evidenced Base Review

Area of Science:

• Pharmacology
• Herbal Medicine
• Drug Interactions

Background:

• Global rise in herbal product consumption necessitates understanding potential herb-drug interactions (HDI).
• Concurrent use of herbal and conventional medicines poses significant therapeutic risks.
• Phytochemicals in herbal products can influence pharmacodynamics, creating complex HDIs.

Purpose of the Study:

• To review and highlight common herb-drug interactions.
• To raise awareness among consumers and healthcare providers about potential risks.
• To identify gaps in current knowledge and guidelines regarding HDIs.

Main Methods:

• Comprehensive literature survey of drug-drug interactions involving common herbal drugs.
• Inclusion of evidence from major databases (PubMed, Embase, Google Scholar) and previous studies.
• Focus on interactions reported over the last ten years, with consideration of older research.

Main Results:

• Data reliability on HDIs can be challenging, but documented case reports aid risk evaluation.
• Self-medication with readily available over-the-counter herbal drugs is a significant concern.
• Existing evidence on HDIs is insufficient, requiring further in vitro and clinical studies.

Conclusions:

• Gathering evidence-based data is crucial for informed patient and consumer knowledge on HDIs.
• Understanding potential adverse events from herb-drug interactions is vital.
• A lack of standardized guidelines for defining and managing HDIs persists.
